THREAD-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 482,308, datedSeptember 6, 1892.

Application filed October 2, 1891. Serial No. 407,583. (No model.)

To all whom/it may concern:

Be it known that 1, CHARLES HILL, of N ewark, New Jersey, have inventeda new and useful Improvement in Thread-Winding Machines, of which thefollowing is a specification.

The machine which embodies this invention is intended for automaticallywinding thread upon spools, and it performs the followingop- 1o erationsupon each one of aseries of spools:

(a) The spool is transferred from a hopper to a spindle, which spindleat this time is not rotating. The mechanism which performs thisoperation I shall call the spool-mount- I5 ing mechanism.

(6) The spool is wound with thread, layer upon layer, each succeedinglayer being longer than the preceding one to fill up to the divergingspool-heads. The mechanism which performs this operation I shall callthe threadwinding mechanism.

(0) Theloose end, known as the scrap end, which is left projecting whenthe winding commences, is cut off. The mechanism which performs thisfunction I call the scrap-endcutting mechanism.

(d) Then the spool is filled, the winding stops automatically andremains stopped until another spool is mounted readyto be 0 wound,whenit is automatically started. The mechanism which performs this operationI call the stopping and starting motion.

(6) The spool-head is slit. The mechanism which performs this operationI call the spool-slitting mechanism.

(f) The thread is drawn into the slit. The mechanism which performs thisoperation I call the thread-securing mechanism.

(g) The thread is cut outside the slit and the end thereof connectingwith the bobbin is held to be in readiness for the commencement of thenext spool. The mechanism which performs this operation I call thethread cutting and holding mechanism.

5 (h) The completed spool is dropped from the spindle. The mechanismwhich performs this operation I call the spool-dismounting mechanism.

(1') Intermediate the windingoperations the thread-guide is moved fromthe end of the longest traverse,where it must stop, to the end of theshortest traverse, where it must start on a new spool. The mechanismwhich performs this operation I call the start-fixing mechanism.

Although in this specification and its claims I shall for conveniencedesignate the various mechanisms as above mentioned or by othercomprehensive expressions, I do not in the use of these expressions wishto be understood as limiting myself to the exact mechanism, either innumber, arrangement, or form of parts, which I shall set forth in moreparticularly describing the machine.

The best form of machine in which I have 6 thus far embodied myinvention is set forth in the following description and the accompanyingdrawings, in which Figure 1 is a plan or top view of the machine. Fig. 2is a side elevation of a portion. Fig. 2 is a detail of a cam 16. Fig. 3is a sectional front elevation showing certain parts. Fig. 4 is a detailshowing a certain cam. Fig. 5 is a front elevation, partly in sectionand on an enlarged scale, illustrating the thread-winding portion of theinvention. Fig. 6 is a plan,partly in section,of the parts shown in Fig.5. Fig. 7 is a transverse vertical section of the parts shown in Fig. 5,the section being taken on the line at m, Fig. 5. Fig. 7 is a detail ofcam 37.

Fig. 12 is a rearsectional elevation taken on the line 10 w, Fig. 10, and showing certain0 parts. Fig. 13 is a view corresponding to Fig.

8 and showing certain belt-shipping mechanism in a position differentfrom that shown in Fig. 8. Fig. 14 is a transverse vertical section of afriction-clutch. Fig. 15 is a front 5 elevation of a device forsupporting and regulating certain parts. Figs. 16 to 22, inclusive,arediagrams illustratingsuccessive steps in treating the thread after thewinding of the spool has been completed and the spin- I00 dies on whichthey are mounted and secured have stopped rotating. Figs. 16 and 17 showthe relative positions of the finger hook, thread-guide, and grip-hookat their extreme throw, having moved simultaneously, also showing theslitting-knife after having cut a slit in the spool-flange and recededslightly therefrom. Figs. 18 and 19 show the relative positions of theabove parts when the griphook has reached its original position and hascut the thread from the spool against a front chisel-edge resilient barand has also gripped the thread from the thread-guide against a rearbar. Fig. 20 is a side view of the ejector in a position about to forcethe spool off the rear spindle, the front spindle having been removed.Fig. 21 is a side view corresponding to that in Fig. 20 and shows theejector in its forward position, having freed the spool from off thespindle and also conveyed, by means of its pin attachment, the threadextended between the hookgrip and the thread-guide to a position to becaughton the shoulder of the spindle. Fig. 22 isa front view of theparts shown in Figs. 20 and 21 and showing by a full line the positionof the thread corresponding to that shown in Fig. 20 and by a dottedline the position of the thread corresponding to that shown in Fig. 21.Fig. 23 is a transverse vertical section of the parts in their relativepositions for receiving a fresh spool.

The main frame consists of two upright parallel plates or bars A and B.From'A projects forward below the spindle-bearings a part 0, whichcarries the slides for many of the parts. From B projects rearwardlyapart D, which carries the cam-shaft 1 and a spindleturning shaft 151.The parts A, B, O, and D are all secured to a bed-plate E, to which isalso secured the mounting of the transverse changing and othermechanism, hereinafter described. This bed-plate E is continuous, andthus unites the bearings of all the mechanisms with absolute firmness.The front edge of the bed-plate E terminates in the same vertical planewith the front of the part A, so that while the bed-plate underlies andsupports those parts of the machine lying to the rear of the spindlesthe spindles overhang the space in front of the bed-plate, and thebedplate thus forms no obstruction to dropping spools when completed.

The spool mounting and dismount ing mechanism.-2 is apositively-revolvedspindle. 3 is a spindle in alignment therewithfree to re volve.Projections 4 and 5 are provided on the ends of the spindles adapted toenter the spool-hole at opposite ends, as shown in Fig. 6. A sleeve orspool-head abutment 6 surrounds the spindle 2 and is pressed towardtheextremity of the spindle by the spring 7. A sleeve or spool-headabutment 8 surrounds the spindle 3 and is pressed toward the extremityof the same by the spring 9. Pins 2 and 3 project from the spindles 2and 3, respectively, into slots in the sleeves, limiting the extent towhich the sleeves may move, the movement of sleeve 6 being much morelimited than the sleeve 8, as indicated by the lengths of slots shown.The end of the sleeve 6 is serrated, as shown in Fig. 23. The setscrew10 forms a back center bearing for the spindle 3 and may be employed,also, to take up wear. The longitudinal adjustment of the spindle 3 iscapacitated by the clamp 12, as-

is also its removal. Itis necessaryfor mounting and dismounting thespool that one of the spindles 2 or 3 should be movable longitudinallyto and from the other, and to this end I mount the bearing or holder 11of the spindle 3 in the clamp 12 upon a bar 13, extending from end toend of the machine, as shown in Fig. 1, and carrying all of the spindles3. This bar 13 is mounted upon the bars 14. and at opposite ends of themachine, and the latter bars are guided longitudinallyin ahorizontalplane by suitable guideways upon the main frame of the machine. Motionis communicated to the bars 14 and 15 by cams 16, mounted upon oppositeends of the shaft 1, which are timed to move the spindles 3 to and fromthe'spindle 2 at the proper instances. The spools to supply each pair ofspindles are held in a hopper 17, extending vertically at one side ofthe spindles and open at the bottom and there provided with theguideways 18 and 19, which are inclined at the angle shown, being anangle of fortyfive degrees. In these guideways is mounted ahopper-bottom consisting of a plate 20, carrying at. its for ward end arabbet 21, so constructed that in one position the plate 20 will closethe bottom of the hopper and in another position the rabbet 21 willcatch any spool falling from the bottom of the hopper, as shown in Fig.5. The bottom of the rabbet is parallel with the guideways. It isnecessary now that means should be provided for reciprocating thehopper-bottom, so that it may carry any spool received in its rabbetfrom below the hopper to betweenthe spindles 2 and 3. This mechanismconsists of a link 22, pivoted at one end to the hopper-bottom and atthe other end to a bar 23, adapted to reciprocate longitudinally in ahorizontal guideway on the' main frame of the machine and extending allthe way across the machine, so as to carry a link 22 for eachhopper-bottom. This sliding bar 23 is moved by a lever 24, actuated by acam 25 on the shaft 1, so constructed as to properly time the motions ofthe hopperbottom. It is necessary, further, to supply an ejector tothrust the spool olf from the end of spindle 2 when spindle 3 recedes.26 is such an ejector, adapted to move parallel with the axis of thespindle from the position shown in Figs. 7 and 19 to theposition shownin Fig. 21. This ejector consists simply of a projection adapted to abutagainst the head of the spool from the longitudinally-sliding bar 27,having suitable guideways in the frame and pivoted to the end ofrock-arm 28, mounted upon the rock-shaft 220, which is actuated inganddismounting mechanisms are actuated are. timed to produce thefollowing results: \Vhen the spindles arein readiness to receive a newspool, the spindle 3 will be in the receded position shown in Fig. 23,and while it remains so the hopper-bottom, carrying a spool in itsrabbet, will be moved from the position shown in Fig. 5 diagonallyupward until the axis of the spool is a trifle below the axial line ofthe spindles 2 and 3, as shown in Fig. 23. WVhile the hopper-bottomholds the spool in this position, the spindle 3 is advanced, itsprojection 5 enters the spool-hole and forces the spool longitudinallytoward the spindle 2 until the projection 4 enters the spool-hole at theopposite end,and the spoolhead is clasped between the spring-presse lsleeve 8 and the serrated face of the springpressed sleeve 6. Theconical form of the projections 4 and 5 will serve to center the spoolwith the axial line of the spindles 2 and 3, and thus slightly raise thespool off of the hopper-bottom, which is then retracted to its firstposition. (Shown inFig. 5.) Then a new spool drops into its rabbet, andit so remains until the spool just mounted is completed. After thewinding of the mounted spool is complete andthe end of the thread hasbeen secured and cut the spindle 3 is receded from the spindle 2, andthe ejector, coming forward, pushes the spool off of the pro jeetion 4and the spool drops into a suitable receptagle below through the openingbetween the bar 13 and the traversing bar 61, over which opening thespindles project transversely. The pressure of the sleeve Sshould beless during the winding operation than it is when the spool is'beingmounted and than it is when the spool is being'slit. Vhen the spool isbeing mounted, the pressure must be so great as to press the teeth ofthe sleeve or arbor 6 firmly against the head of the spool, and again,when the knife comes forward to slit the spool-head, so that thepressure of the knife will be fully opposed by the pressure of thesleeve 8; but when the thread is being wound to prevent the heating andwearing of the spindles it is desirable that the pressure of the sleeve8 should be lessened. All of these three conditions are accomplished bythe form of the cam 16, which, as shown in Fig. 2, is slightly flattenedat and nearits center, (between the points 224 and 225,) so as to allowthe bar 13 a slight retreat under the combined pressures of the springs9.

The spoolsl'iitt'ng mec7tam'sm.-As soon as the thread-winding mechanismhas completed its function and stopped it is necessary that one flangeof the spool should receive the customary slit, which I accomplish bymeans of a knife 29, located in the plane of a chord of the periphery ofthe spool-flange, as shown in .the spool barrel.

Fig. 5, and extending so as so intersect the periphery sufiiciently tomake the depth of slit required. This knife projects in a horizontalplane from the head 30, being held in a horizontal slot therein. Thehead is, as clearly shown in Fig. .7, mounted upon the end of alongitudinally-sliding rod 31, provided with suitable guideways in theframe and connected by a link 32 to an arm 330, connected with arock-shaft 340, which receives motion through the downwardly-extendingarm 350 and the connecting-rod 56 from the cam 57 on shaft 1. The arm330 is connected withthe shaft 340 by being pivoted to an intermediatearm 58, fast on rock-shaft 34.0, and held from vibrating by theset-screws 59. By these set-screws the adjustment is made to take up thewear of the knife. The knife is also made adjustable in the slot on thehead 30 to accommodate different sizes of spoolheads. The point of theknife is beveled so as to cut the spool-flange to the angle at which thethread will be pulled into the slot. 57 is a double-throw cam so timedthat when the winding is completed the knife advances and makes its outto the full depth, then recedes.

about on e-eighth of aninch, or just far enough to allow the thread toget into the slit while still acting to guide the thread in, thenrecedes again after the thread is in the slit to its normal position.The form of this cam is illustrated in Fig. 7. The slot in which theknife is held being parallel with the guideways of the knife-bar, theknife will always be held in its plane of movement and requires noadjustment to make it cut in a uniform direction.

The thread-securing 'mec7zam'sm.As soon as the spool-flange has beenslit by the knife before described and after such knife has beenpartially but not wholly retracted from the slit, it is necessary thatthe thread between the thread-guide and the spool should be inserted andforced into the slit, so as to be held therein. To this end I provide anoscillating finger 33, the normal position of which is shown in Fig. 7,and the subsequent positions of which are shown in Figs. 16 to 19. Thisfinger is of the form shown, being provided with a hook on the end. Itis mounted upon a rock-shaft 31, to which a rocking motion iscommunicated from the cam 35 on the shaft 1 through the lever 36,connecting-rod 37, and the crank 38. This crank is so timed as to givethe finger the following motions: The finger 33 rocks downward when theknife has slit the spool-flange and partially retreated from the slit.In its descent the finger catches the thread extending from thethread-guide to that end of the spool-barrel next the slitted flange,the stop motion having stopped the thread winding at the end of Thefinger swings above the knife 29 to a position slightly below the planeof the upper surface thereof, as shown in Fig. 17, so as to lay thethread on the flat upper surface of the knife and in position to beseized by the hook 39, which draws the thread taut across the peripheryof the spool-flange while the knife-surface guides it into the slit.While the finger 33 holds the thread in the position shown in Fig. 17,the thread-holding mechanism, whichI will next describe and of whichhook 39 is a member, advances and relieves the finger of the thread andthe finger returns to its normal position (shown in Fig. 23) and remainsthere until another spool has been wound and slit. By having the fingeroscillate instead of reciprocate,I am enabled to carry the thread downfor enough for the hook 39 to grasp it with absolute certainty.

The thread cutting and holding mechanism.-As soon as the thread has beensecured in the spool-split it is necessary that it should be out betweenthe spool and the thread-guide and that the end thus formed next thethreadguide should be held in proper position to enable the winding of anew spool to be started automatically. To this end I provide areciprocating hook 39, the path of which is just outside the aretraversed by the finger at a point above the lowermost position of thefinger, so that while the finger is down the thread between the flangeand thread-guide will be drawn downinto position to be caught by theholding-hook 39, as shown in Fig. 16. The holding-hook 39 is mountedupon a slide 40, adapted to reciprocate in horizontal guideways in themain frame. This slide 40 carries the holding-hooks for all the spindlesand is reciprocated by a lever 41, actuated by a cam 42 on the shaft 1.In receding after having grasped the thread the holding-hook 39 retreatsbetween two cheek-plates 43 and 44, which exert a spring-pressureagainst the sides of the hook 39 and one of which 43 is longer than theother 44. The thread will first be clamped between the plate 43 and theside of the hook 39, and as the hook retreats farther the thread whilestill clamped and held on that side of the hook will on the other sideof the hook be brought against the chiseledge of the plate 44 andthereby cut. Thus the spooled thread is cut loose from the thread yet onthe bobbin and the end of the unspooled thread is held between the hook39 and the cheek-plate 43, as shown in Fig. 20. It is still necessarythat the end of the unspooled thread be brought into such position as tobe held by a newly-mounted spool and to turn therewith. To this end Iprovide upon the ejector 25 a pin 45, projecting downward, so that thethread extended between the thread-guide and the cheek-plate 43 will liein the path of this pin as the pin is carried forward by the ejector.The pin therefore catches the thread and carries it beyond the serratedend of the sleeve 6, so that'when the pin retreats the thread will lieacross the serrated end of the sleeve 6, as shown in dotted lines inFig. 22. Now obviously as soon asa new spool is mounted the end ofthread coming from the thread-guide will be clamped between thespool-head and the serrated end of sleeve 6. By mechanism hereinafterdescribed the thread-guide at the commencement of the winding of a newspool will be opposite the junction between the flange and barrel of thespool. Therefore the thread will extend from where it is held betweenthe spool-head and the end of sleeve 6 over the flange of the spool tothe thread-guide, and as soon as the spool commences to turn will bewound upon the barrel thereof, leaving a projecting end extending outfrom the barrel and over the spool-head. To cutoff this end, which iscalled the scrap end, is the object of the mechanism which I will nextdescribe.

T he scrap-end-cuttt'ng mechanism-46 is a knife mounted upon an arm 47,pivoted to the frame at 48 and rocked by the reciprocation of a slide49, from which motion is communicated to the arm 47 through the pin 50and the arm 51. The slide 49 (which has the same connection with a knife47 for each spindle) is connected with a lever 52 by a bolt 53 andalink230. Oscillating motion is given this lever through a rod 231 and a pin232 from a cam 233 on the shaft 147, in antagonism to which cam thespring 234 acts. The knife 46 is made adjustable on the arm 47 by meansof the set-screw 54 and vibrates between a position where its edge is incontact with the flange of the spool, as indicated in dotted lines, Fig.7, and the position shown in full lines in Fig. 7. The parts from whichthis knife receives its motion are so timed that the edge of the knifeis pressed against the flange of each spool immediately after thewinding of the spool has commenced. This cuts oh the end of the threadswhich passed from the barrel of the spool over the flange to the holdingcheek-piece 43, and as soon as the hook 39 again advances thecheek-piece loosens its hold upon the end of thread and it drops intoany suitable receptacle below. Having accomplished this function, theknife 46 rises again in time to be out of the yvay of the thread beingwound upon the spool. It is insured that the scrap ends will not clogthe machine, because the hook 39 moves horizontally, and each time itadvances it pushes out from behind the cheek-piece the scrap end which.it drew in when it previously retreated.

The thread-winding mechanism-55 is the thread-guide, which isconstructed and mount ed on the same principle as described in LottersPatent granted to me, No. 413,447, dated October 22, 1889. Thethread-guide and the parts connected with the same are mounted upon astandard 60, which is fixed upon a laterallyreciprocating frame 61,vibrated by longitudinallyrreciprocating bolts 62 and 63, havingguideways in boxes 64, mounted upon the main frame. These bolts connectthe frame 61 with a yoke 65, from the middle of which yoke projectsrearwardly the rod 66, mounted in bearings, enabling it to reciprocatelongitudinally and hearin g a carriage 67, which is fixed upon the rod66 by the setscrew shown in dotted lines in Fig. 12. The carriage 67bears a screw-threaded nut 68, bolted to the carriage, within which nutturns a shaft 69, having an external screw-thread at 7 O, which engageswith the screw-tn read of the nut 68. The shaft 69 is mounted insuitable bearings, by which it is fixed longitudinally, and it carriesupon one end the beveled gearwheel 71, which meshes with the beveledgearwheels 72 and 73, which turn freely upon the shaft 74, excepting asmotion may be communicated alternately to one or the other of the gears72 and 73 by the clutch 75, splined to the shaft 74 between them. Theshaft 74, while the winding is in progress, is continually revolvedthrough the line of gears 76, 77, 78, 79, and 80, the pulley 81, thebelt 82, pulley 83, the shaft 84, the pulley 85, fast upon it, the belt86, and the pulley 87, which is driven by the engine. 88 is an arm bywhich the clutch 75 is shifted alternately into engagement with thebeveled gear-wheels 72 and 73 and which arm is mounted upon alongitudinally-reciprocating rod 89, the end of which is pivotallyconnected with a rocking arm 90, fixed upon a vertical shaft 93, uponwhich vertical shaft 93 is fixed a finger or dog-head 94. The point ofthis dog-head is V- shaped and engages with a V-shaped projection 95 onan arm 96, pivoted at 97 to the slides 98, and pressed against thedog-head 94 by the springs 99 and 100. The slide 98 is free to slidebackward and forward in the (lirection of the arrow 101, Fig. 10, andcarries the fingers 102 and 103, which are adjusted to slide to and fromeach other and which together constitute a shaper, the angulardivergence of and distance between their adjacent sides timing thechanges of traverse. The carriage 67 also bears an arm 104, whichcontains a slot 105, engaging with a stud 106 on the carriage. Thecarriage 107 is mounted so as to be free to reciprocate in the directionof the arrow 101, Fig. 10, upon a table 302, provided with a slot forthat purpose. The table 302 is carried by frictionrollers 108 and 109,so as to reciprocate in the direction of the arrow 110, Fig. 12.Connected with one side of this table is a rod 111, mounted in bearings,enabling it to reciprocate with the table, and to the end of this rod isconnected the cord 112, carrying the weight 113, which exerts a constantpull on the rod and on the table connected therewith. Upon the carriage107 is mounted a stud 114, which extends upwardly between the fingers102 and 103 of the shaper. I

The operation of the thread-winding mechanism may be described asfollows: It is apparent that the thread-guide is compelled to move inunison with the yoke and that this yoke must be moved backward andforward in the direction of the arrow 115, Fig. 8,

and that its length of traverse must be increased at every change oftraverse in order to accommodate the flare of the spool-heads, and it isto convert the rotation of the pulley '87 into the traversing motions ofthe yoke 65 and its connected rod 66 that is the object of the mechanismwhich has been just described. The continuous rotation of the pulley 87is conveyed through the train of belts, pulleys, and gears, alreadyreferred to, to the shaft 74, which is continuously rotated. Thecontinuous rotation of the shaft'74 is communicated to the shaft 69, soas to turn the shaft 69 alternately in opposite directions, dependingupon whether the clutch engages with the beveled gear 72 or the beveledgear 73. When the shaft 69 revolves one way, the carriage 67 willtraverse in one direction, and when the shaft revolves the other way thecarriage will traverse in the other direction. Therefore it only remainsto provide automatic means for shifting the clutch 75, in order toproduce the requisite changes of traverse. The operation of thisautomatic mechanism is as follows: The stud 114, being connected withthe stud 106, is compelled to traverse backward and forward with thecarriage 67. As it traverses forward it will strike the finger 102 andas it traverses backward the finger 103 of the shaper. \Vhen it strikesfinger 102, it will shove that finger and the slide 98 and the arm 96forward with it, and the reverse operation takes place when it strikesfinger 103. In Fig. 10 the V-shaped projection on the arm 96 and thedog-head 94 are shown in the position they occupy when the traverse isbackward or toward the finger 103. WVhen now the stud 114 strikes thefinger 103 and thereby shoves the arm 96 backward, the first eifect willbe that the incline of will slide up on the incline of 94 until it haspassed the apex thereof, whereupon the springs 99 and will press theopposite incline of 95 against the oppositeincline of 94, so as to swing94 back to the opposite end of its stroke. As, however, the finger 94 isswung it will shift the clutch 75 from engagement with one gear-wheel toengagement with the other, where it will remain until the stud 114 hasmoved into contact with and shoved the finger 102. When this occurs, theV-shaped projection 95 will be on the opposite side of the dog-head 94,and as it is carried backward it will swing the dog-head 94 back intothe position shown in Fig. 10, thereby again shifting the clutch andplacing the parts in position for producing the next change of traverse.Thus when the stud 114 shoves either member of the shaper the dog-head94 is tripped backward or forward and the clutch 75 is shifted so as toproduce the change of traverse; but it is necessary, also, that eachtraverse should be made longer than the preceding one, and it is evidentthat this may be accomplished by moving the stud 114 so that itconstantly advances toward the extremity of the shaper, and thus, owingto the flaring sides of the shaper, has constantly a longer distance totravel before it ,commences to push either of the fingers thereof.

The tendency of the weight 113 is obviously to pull the carriage 107,bearingthe stud 114, in the direction of the arrow 110, Fig. 12;but thecarriage is drawn in the opposite direction in antagonism to the weightby a yoke 116, fixed at one end upon the rod 111, and mounted at itsopposite end in a horizontal guideway 117 and provided with alaterallyprojecting pin 118, which rests against a crown-cam 119. Tothis cam is fixeda ratchet-wheel 120, actuated by the pawls 121 and 122,each of which is pivoted to the opposite extremity of a rocker 123,centrally fixed upon a shaft 300, having its bearings in a standard 124on the frame. Upon the opposite end of this shaft is fixed theoscillating arm 125, the extent of oscillation of which in bothdirections is limited by the adjustably-fixed setscrews 126 and 127. 128is a rod pivoted to the arm 125 and connected by the stud 129 with adisk 130, clamped face to face with a disk 131 by a central holt132.Acircular recess 133 is turned in the face of the disk 131, which isfilled with an annulus 1340f leather or other material suitable for afriction-surface, also with an annulus 135 of suitable metal to form africtional contact with the leather. The latter annulus is held fromrotating on the disk 130 by a pin 136, and two or more set-screws, as137 and 138, are provided for setting the annulus 135 up against theannulus 134, thus forming substantially a frictional clutch. The disk131 is fixed to the yoke 65, and as this yoke reciproeates in thedirection of the arrow 115, Fig. 8, the clutch compels the rod 128 toreciprocate with it in both directions, until on the forward traversethe arm125 strikes against the setscrew 126, and until on backwardtraverse the arm 125 strikes against the set-screw 127. As soon as thisarm strikes against either setscrew'the friction between the disks 130-and 131 is overcome and the movement of the rod 128 will stop until thetraverse changes. The set-screws 126 and 127 will be adjusted so thateach of the pawls 121 and 122 will be moved alternately exactly thedistance for it to engage a new tooth of the ratchet-wheel120. Infactory parlance the ratchet wheel 120 is called the row-cam, because itcontrols the number of rows of thread wound on the spool, two rows orlayers being wound for each tooth. Therefore this row-cam is changed asthemachine is required to wind different numbers of rows, and for eachchange of the row-cam the set-screws 126 and 127 must be adjustedcorrespondingly.

In the automatic machines heretofore used the threadguide was liftedonly once for every two rows of thread. Therefore the extent to which itwas lifted was made the means between that required for each row, andhence one row would be wound loose because of too little pressure andthe next tight because of too much pressure. In my machine, on thecontrary, it will be observed that the row-cam and its co-operatingmechanism causes the thread-guide to be receded at the commencement ofeach row. This not only benefits the quality of the work done, butincreases the speed of the machine, because the equality of pressurediminishes the tendency to burn or break the thread when running at ahigh speed. Now it will be evident that on the forward traverse of theyoke the pawl 122 will rotate the ratchet-wheel 120, and that on thebackward traverse the pawl 12 1 will rotate the ratchet-wheel120.Therefore the ratchet- Wheel 120 will move intermittently on each 7traverse, and likewise the cam 119. This produces a corresponding motionin the yoke 116, the rod 111, the carriage 107, and the stud 114 inantagonism to the weight 113, and thus intermittently the stud 114 is oneach traverse moved nearer to the extremity of the shaper, and therebygiven a longer distance to travel on each succeeding traverse than onthe preceding one before giving the shove to the shaper which isnecessary for changing the traverse. The shaft of gear 79 is mounted ina slot concentric with gear 78, so that it admits of difierent-sizedgear being used for difierent-sized thread without altering the distancebetween the centers of the belt 82; also, the pulleys 81 and 83 are madeconical, so as to take up the pitch of the fraction of a tooth if thesize of thread requires it.

I have now described the parts and the operations necessary forimparting to the yoke 65 the traverses, which grow successively longerfrom the commencement of the spool to its finish, which traverses arecommunicated to the bar 61., carrying all the threadguides. It isfurther necessary to manipulate the thread-guides so that each of themautomatically retreats from the barrel of the spool as the threadaccumulates thereon until the last two (more or less) traverses arereaeh'ed,when it is necessary that the threadguide should press againstthe thread with sufficient force to give it the external smoothappearance necessary for a marketable article. For thus manipulating thethread-guide the following means are provided: The standards 60 for thethread-guide, instead of being fixed directly upon the bar 61,are fixedupon slides 139 and 140, having suitable longitudinal guideways in thebar 161. These slides are urged in the direction of the arrow, Fig. 3,by a weighted lever 141, acting through the cord 142, so that when thepull of this cord upon the slides-139 and 140 is unopposed the fullpressure derived from the weighted lever will be distributed among thethread-guides and delivered by them on the spools. To shove the slides139 and 140 in antagonism to the weighted lever 141 during all thetraverses except the last two, (more orless,) a scroll-cam 143 isarranged to operate upon a roller 235, mounted on the slide 140. Thisscroll-cam 143 is fixed upon a shaft 147, which receives motion throughthe beveled gears 148 and 149 from the shaft 150, being the same shaftupon which are fixed the intermittently moving ratchet-whee1120 and cam119. Therefore the scroll-cam 143 will be moved intermittently on eachtraverse, and it is so constructed that for each movement it causes thethread-guide to retreat the thickness of a layer of thread on eachtraverse until the last two, (more or less.) when the roller 235 willfall off the point of the cam and the subsequent retreat of thethread-guide will be due to the accumulation of thread which will bearthe pressure of the weighted lever 141. Obviously the scrollcam 143 willbe changed for different sizes of thread. The thread-guide is adjustablysecured bya set-screw 236 and slot to a support 237, pivoted to the stud60, so that the operator may at any time throw it back into the positionshown at the left of Fig.5. It is held either thrown back or thrownforward by a latch 238, engaging with a stud 301 on the tail of thesupport 237; but when winding it occupies the forward position. (Shownat the right of Fig. 5.) Each of the spindles 2 is rotated from theshaft 151 through the beveled gears 152 and 153, and the shaft 151 isdriven by the beveled gears 154 and 155 from the shaft 84, upon whichthe pulley 85 is fixed. Each spindle has a bearing in the two branches Aand B of the main frame. To take the thrust of mounting the spools, Iprovide in front of the back bushing 277 a friction-washer 278, in frontof which are placed the locknuts 279 and 280. While the thread-windingis in progress the thread-guide support is forward, as shown at theright of Fig. 5; but as soon as the winding is finished it is necessaryfor this support to be moved backward automatically, so that thethread-guide will be out of the way of the other operations. This isaccomplished by a cam 212 on shaft 1, which connects with slide 139 140by a lever 213, pivoted to the stud 214. While the winding is inprogress and the cam 212 is stationary, this lever rests in a notch inthe cam, as shown in Fig. 1; but while the shaft 1 revolves the lever israised out of this notch and the thread-guides are thus shoved back, asrequired.

Stopping and starting motions-The object of the stop-motion is to shiftthe belt 86 from the pulley 85, fast on the shaft 84, to the loosepulley 157, which is fast upon the sleeve 172, carrying the worm 164,and at the same time to apply a brake-strap 158 to the pulley 159, whichis connected to the pulley 85. As the pulley 85 turns, the shaft 84, onwhich it is fixed, at the same time drives the spindleturning shaft 151,and the belt 82, by which the traverse actuating and changing mechanismis run. As the pulley 157 turns, the sleeve 172, to which it is fixedthrough the worm 164 and the worm gear 165, drives the shaft 1, fromwhich are taken the motions which which are in operation while thewinding is suspended and which shaft 1 makes a complete revolution eachtime the windingis suspended. 160 is the belt-shifter, which isconstantly urged inthe direction of the arrow 161 by the weight 162,acting through the cord 163. The belt-shifter 160 slides upon a bar 167,and this bar in.turn slides in guideways on the frame. A pin 168 fromthe bar 167 projects into a slot in the belt-shifter 160, as shown inFig. 8. The bar 167 is constantly urged in the direction of the arrow169 by the weighted lever 170, and the weight 171 on this lever issufficient to overbalance the weight 162 and move the sliding bar 167and the belt-shifter 160 from the position shown in Fig. 8 to that shownin Fig. 13. While the operation of winding is in progress, a hook 174engages with a notch in the sliding bar 167 and prevents its fromyielding to the weighted lever 170. It will be remembered, however, thatthe shaft 150 moves during the winding operation intermittingly onceduring each traverse and that it makes one complete revolution for eachcomplete winding operation. This motion is imparted to an arm 175, fixedupon it and carrying adj ustably secured in a slot the pin 176. 177 is alever resting, normally in the position shown in Fig. 8, upon a stud178, which it carries, but having an adjustable point 179 at itsopposite extremity which projects into the path of the pin 176, so

that the lever 177 is tripped into the position shown in Fig. 13 oncefor each rotation of the shaft 150. On the top of the lever 177 rests apin 180, sliding freely in a stock 181, which is pivoted at 182 andprovided with a laterally and upwardly projecting arm 183. This pin 180extends entirely through the stock 181 and is forced upward, so as toproject farther above the stock, as shown in Fig. 13, by the lever 177as the latter rises. hen the pin 180 is in it's lowermost position, itis not within the path of the movement of the rod 184; but when it is inits raised position it projects within the path of the movement of thatrod. The rod 184 is mounted at one end with capacity for longitudinaladjustment upon the traversing yoke 65 and projects through suitableguideways toward the top of the pin 180 when in its highest position.When therefore the pin 180 is raised, the next backward traverse of theyoke 65 will cause the rod 184 to shove the pin 180 over into theinclined position shown in Fig. 13, so as to raise the arm 183 and thearm 144 resting on it, by which the hook 174, which is connected withthe arm 144, is tripped out of the notch in the slide 167 and the slideshoots from the position shown'in Fig. 8 to that shown in Fig. 13,dragging the belt-shifter with it, so as to shift the belt'from pulley85 to pulley 157 and permit the nose of the lever 185 to fall behind theprojection 186 on the belt-shifter and hold the belt-shifter in thatposition against the impulse of the weight 162 even after the slide 167has been returned to the position shown in Fig. 8, which is accomplishedas follows: On the shaft 1 is a collar carrying the projection 187. Alever 188, pivoted at 189, is arranged so that one arm in one positioncomes within the path of the projection 187. The other arm of the le-IIO ver 188 is pivotally connected by a link 190 with one arm of thelever 191, pivoted at 192, and carrying upon its opposite arm thefriction-roller 193, which bears against the side of the upper arm oflever 170. Now as the projection 187 is carried around by rotation ofshaft 1 it will strike lever 188 and thrust it from the position shownin Fig. 13 to that shown in Fig. 8, compelling the slide 167 to returnto the position shown in Fig. 8, where it is seized and held by the hook174:. 1941is a projection upon the shaft 1, adapted to strike the lowerarm of the lever 185 as the shaft 1 rotates, and after the shaft hasrevolved, so that the projection 187 has thrust the slide 167 into theposition shown in Fig. 8, the further otation of the shaft soon bringsthe projection 194 under the tail of the lever 185, so as to lift thenose of that lever from behind the projection on the belt-shifter andpermit the belt-shifter to be pulledby the weight 162 back into thepOSitiOIl'SllOWIl in Fig. 8. To the rear end of the slide 167 is fixed abracket 195, and this in turn carriesa wedge 196. This wed ge projectsthrough a slot in the bolt 197, connected with one end of the brake-band158. When the slide 167 moves forward in the direction of arrow 169, itadvances the wedge 196 in its slot and brings the brakeband 158 downupon the pulley 1.59 and stops the shaft St and all thcthread-windingand traverse-changing mechanism connected with it. The brakeband isloosened by the retreat of the wedge with the backward movement of theslide 167. 198 is a friction-block fixed with capacity forback-and-forth adj ustment upon abracket 199, fixed upon thebeltshifter-160. This friction-block 198 is beveled and provided with acooperating beveled friction-surface at the edge of the fiange of thepulley 157, so that when the belt-shifter is in position to throw thebelt on pulley 85 the friction-block 198 will act as a brake on thepulley 157 and stop that pulley and the shaft 1 and the other mechanismconnected therewith; but when the belt-shifter is in position to throwthe belt on pulley 157 the frictionblock will be out of contact with thelatter pulley. A non-automatic stop motion is also provided, whichconsists of the belt-shifter 209, operated by the hand-lever 210 throughthe rock-shaft 211.

Start-fitting mecltcmism.\Vheu the spool has been wound, it leaves thethread-guides in line with the periphery of the spool-head, or, in otherwords, at the end of the longest traverse. When news'pools are insertedand the winding recommences, the thread-guide must be in line with thebarrel of the spool, or, in other words, within the bounds of theshortest traverse, and the mechanism about to be described is for movingthe thread-guide intermediate the winding operations from the end of thelongest traverse to within the bounds of the shortest traverse. Theshaft 1 is connected by the gears 200 and 201 with the shaft 202,carrying the eccentric connecting-rod 203, which oscillates the arm 201,fixed on the shaft 205. 206 is another arm fixed on the shaft 205 andoscillating therewith and to which is pivoted a pawl 207, engaging witha ratchet-wheel 208, fixed to the beveled gear-wheel 72. Now through thechain of mechanism just described the beveled gear 72 will be rotated asthe shaft 1 makes its revolution, so as to move the thread-guides upontheir backward traverse the proper distance, for the purpose above setforth. In practical operation, however, something more is necessary,because the practice is to stop the winding just short of the end of thespool, and therefore just before the dog-head 9t has passed over theV-shaped projection 95, which it is necessary that it should pass overfor the start-fixing mechanism to properly perform its function. Tocause this result, I provide on the shaft 1 a projection 275, which asthe shaft revolves will strike a projection 276 on the slide 98 and kickthat slide over far enough to throw the dog-head 94 on the opposite sideof the V-shaped projection 95 to that shown in Fig. 10. In prac: ticethe winding will stop before the pin 118 has passed over the highestpoint of cam 119, and it is necessary that this cam should be movedenough for that purpose while the winding is suspended, so as to allowthe stud 111 to move back into position for the short traverse of thenext winding operation. To this end I provide on the shaft 1 aneccentric pawl 281, engaging with the ratchet-wheel 282 on shaft 150.Each revolution of shaft 1 will cause the pawl to turn theratchet-wheel, and consequently cam 119, just far enough for the purposeindicated.

Among the many features combined in my machine may be mentioned thefollowing: The spindles run transversely of the machine and the lengthof space occupied by them is less than five and a half feet, the totallength of the machine being only six feet. By confining the spindleswithin this space the 0perative standing in the center may reach all thespindles without walking. The shaft 69 being arranged below the shaft 81, one does not project materially farther backward than the other andthe depth of the machine is thus limited. The spindles are securelyjournaled and can be removed with great convenience. The spools are heldover an open space, through which they are dropped. The spindle-drivinggears are entirely out of the way at the back of the machine. Thethreadguides are so located that the spools are open to inspection fromabove at all steps of the winding. The non-reciprocating spindlesproject side by side from the front of a stationary frame, in whichtheir bearings may be prolonged to any extent. The reciprocatingspindles project inversely from the front bar of a three-sided frame,the two end bars of which slide on the stationary frame and connect withthe cams at their extremities. The thread-guides are mounted on thefront bar
